Bus traffic displays use color and graphics to show captured transactions.
Packets are on separate rows. Packets receive time stamps and sequential numbers as
the system records them. Fields have labels and color codes. The system automatically
detects protocol errors and highlights them in red.
You can customize the display color scheme and field formats. You can use the hide
feature to suppress SOF packets and uninteresting user-defined packets or fields in
different contexts. You can name and save display formats for later use. Pop-up tooltips
annotate packet fields.
The display software operates independently of the hardware, allowing it to function as a
stand-alone “trace viewer” that you can freely distribute.

1.1.2 Accurate Time Measurement (Voyager, Advisor T3)
The internal counter/timer circuitry enables reliable, accurate (2 ns resolution)
time stamping of recorded bus traffic. Traces and measurement and analysis functions
display this timing information. Time fields are time stamps, idle times, bit times, or time
deltas, in either decimal or hexadecimal format. You can add any number of markers to
denote specific packets, you can make further timing measurements from one marker to
another or from marker to trigger.
An essential feature of time management is that idle traffic does not consume Analyzer
memory. Because of this unique technology, the system can make accurate timing
calculations while still preserving valuable recording memory for important bus traffic.
The oscillator has 2.5 ppm accuracy.
1.1.3 CrossSync Control Panel (Voyager, Advisor T3)
The LeCroy CrossSync control panel provides synchronization for complete end-to-end
visibility into multi-protocol systems.
CrossSync is LeCroy’s analyzer synchronization solution that enables time-aligned
display of protocol traffic from multiple daisy-chained analyzers showing packet traffic
from multiple high-speed serial busses. A lightweight software control panel allows users
to select analyzers for synchronization and manage the recording process. Captured
traffic is displayed using the latest analyzer software (in separate windows) with all the
protocol specific search and reporting features.
Captured packets are displayed in separate windows that share a common time scale.
Navigating the traffic in either direction will scroll to the same timestamp in a
synchronized window. When using the CrossSync option, users can access the full
complement of analysis capabilities available within the individual LeCroy software.
Search, reporting, and decoding all operate normally.
This feature is available with the LeCroy USB Protocol Suite application.
1.1.4 Comprehensive Error Detection and Analysis
The system detects, and alerts you to, every potential bus error and protocol violation,
and their combinations. The Analyzer BusEngine™ circuitry performs real-time triggering
on multiple error conditions, such as PID bad, bit stuffing bad, header or data CRC bad,
end-of-packet bad, babble, activity loss, frame length violation, time-out or turn-around
violation, and data toggle violation. The Analyzer program highlights all
hardware-detected errors and further examines the trace file for additional
protocol errors, including wrong packet length, data payload violation, and
packet termination not on a byte boundary.
2LeCroy Corporation
USB Protocol Suite User ManualChapter 1: Overview
1.1.5 Real-Time Event Triggering and Capture Filtering
The Analyzer can accurately identify and selectively record transactions of interest from
the crowded stream of bus traffic. The system uses more than a dozen configurable
hardware building blocks that you can optimize to perform particular activities. Such
“recording resources” can independently await an initialization signal, monitor its external
environment (external signals or other resources) in search of a particular event, and take
a subsequent action, such as triggering, inclusive or exclusive filtering, and counting. In
the user interface, you can select, configure, and combine these resources to search for
complex trigger conditions and selectively capture associated transactions.
The system can trigger on basic events, such as specific bus conditions and
packet identifiers (PID). It can also trigger on complex events, such as “trigger on the
fifth occurrence of a SETUP Token device number nine” or “trigger on a SET INTERFACE
request, following a specified eight-byte bulk data pattern match from this scanner, and
do not capture any start-of-frame (SOF) packets.”
You can set the size of the recording memory, specify the pre-trigger to post-trigger
capture ratio, and truncate large data packets up to 256 bytes.
1.1.6 Advanced Event Counting and Sequencing
The count and sequence options define rules for data recording sessions. These options
configure and control the order of events selected for triggering or filtering.
Using this feature, you can specify a sequence of up to seven events that must occur
before the Analyzer triggers and finishes capturing data, allowing you to specify
event types for recording. Without this feature, you may have to scroll through megabytes
of recorded data to locate an occurrence of a sequence.
1.1.7 BusEngine Technology
The Analyzer uses LeCroy BusEngine Technology. The BusEngine core uses Electrically
Programmable Logic Device (EPLD) technology and incorporates both a real-time
recording engine and configurable building blocks that implement data/state/error
detection, triggering, capture filtering, external signal monitoring, and event counting and
sequencing. Like the flash-memory-based firmware that controls its operation, all
BusEngine logic is fully field upgradeable, using configuration files.

1.2.1 Voyager M3 General Description
The Analyzer connects to a portable or desktop PC through the USB port. The PC
configures and controls the Analyzer. The “CATC Trace™” user interface is an industry
standard for documenting the performance of high-speed serial protocols.
The USB protocol Analyzer provides traffic capture and analysis. Hardware triggering
allows capture of real-time events. Hardware filtering allows filtering different packet
types in or out of the recording. Filtering also allows you to preserve recording memory,
for extended recording time.
The trace viewer application displays recorded data in colored graphics. The application
has advanced search and viewing capabilities that allow you to quickly locate specific
data, errors, and other conditions.
The system functions with any personal computer having the Microsoft
Windows Vista™ 32, Windows Vista 64, or Windows 7 (32 or 64) operating system and
a functional USB interface or Ethernet port.
The system provides on-the-fly detection of, and triggering on, such events as Tokens
and Errors. Whether recording manually or with a specified trigger condition, the system
continuously records the link data, in a wrap-around fashion, until manually stopped or
until the system detects the Trigger Event and records the specified post-trigger amount
of link data.
Upon detection of a triggering event, the Analyzer continues to record data up to a point
specified by you. You can individually enable or disable real-time event detection to allow
triggering on events as they happen, including predefined exception or error conditions
and user-defined sets of trigger events. An externally supplied signal can trigger the
Analyzer.

1.2.4 Traffic Generation
USB 2.0 and 3.0 traffic generation options allow you to transmit custom packets over
standard USB cables with low-level control of headers, payloads, timing, and link states.
The Exerciser can play back trace files bit-for-bit, allowing validation engineers to
recreate problems reported in the field or test-specific functionality.
To build generation script files, you can edit example test scenarios or export any traffic
stream from a previously recorded trace. The Voyager Exerciser includes a
Generation Script Editor.
A script pre-processor allows you to organize script code and create reusable generation
blocks.
For USB 3.0 applications, test scenarios can contain multi-stage traffic generation blocks
that include Boolean expressions, LOOP, DO-CASE, and IF-THEN logical branching.
The Voyager USB 2.0 Exerciser can transmit low, full, or high-speed traffic and supports
both host and device emulation. It is backward compatible with existing USBTra i n e r
traffic generation scripts.
For USB 2.0 applications, the Exerciser supports both bitstream mode or Intelliframe
mode. In Intelliframe mode, the Exerciser can wait for the appropriate response from the
DUT before transmitting the next packet. For example, after issuing an IN, the generator
waits for the DATAx packet returned by the device to finish, and then issues an ACK.
When NAKs are received, the Exerciser can automatically resend the previous packet.
Voyager ReadyLink™ Emulation
The LeCroy Voyager USB 3.0 Exerciser features ReadyLink Emulation Mode. The
ReadyLink feature handles all USB 3.0 link training and link flow control, allowing the
emulator to operate at full line rate and respond to the DUT as defined by the
specification. The ReadyLink Emulation Mode helps simplify development of USB 3.0
test scenarios.
By default, ReadyLink Emulation Mode automatically manages:
•Header Packet Acknowledgements (L_GOOD_n)
•Buffer Credit (L_CRD_x)
•SKIPs at required intervals (SKP)
•Link Synchronization
•Responds to LFPS (Polling.LFPS)
•Responds to polling sequence (Polling.RxEQ)
•Responds to TS1 / TS2 handshaking sequence
•Responds to SS.Inactive (with RX.Detect)
•Power Management Link Commands
•Responds to LGO_Un (with LAU)
•Responds to LAU (with LMPA)
10LeCroy Corporation
USB Protocol Suite User ManualChapter 1: Overview
Test scripts can customize ReadyLink Emulation Mode to include error scenarios, such
as:
•Header LBADs
•Invalid link commands
•8B10B / CRC Error
•Running Disparity Error
•Corrupt Link Commands
•Corrupt Flow Control (Wrong L_CRD_x, Wrong L_GOOD_n, Drop L_Good_n)
At the packet level, you can send customized data payloads anywhere within the stream
to insert logic errors, perform corner-case, or do stress testing. Commands, such as the
Set ErrWrongLCRD command, allow link-layer error injection anywhere within the script.
1.2.5 Notes on LFPS Signals
Voyager Exerciser requires received “Ping” LFPS signals to be a minimum of
150 nanoseconds to be reliably recognized.
Voyager Analyzer can recognize “Ping” LFPS signals above 60 nanoseconds and report
their durations to
±15 nanoseconds of accuracy.

3.4 Cascading with CATC SYNC Expansion Card
You can cascade two Analyzers, if they both have a CATC SYNC port:
•Voyager requires a CATC Sync Expansion Card for cascading.
•Advisor T3 has a built-in CATC SYNC port and only requires a cross-connect
or octopus cable accessory.
After Analyzers are connected, recording will start simultaneously and triggers will occur
simultaneously, with synchronized timestamps.
You must select both Analyzers in the Device List dialog
(see “Analyzer Devices” on page 57).
Important: When you are NOT doing cascaded recording, you must UNPLUG the cable!
If you do not unplug, the electrical signal prevents recording on all Analyzers.
Note: In this software version, cascaded recording only works if you use two Voyagers
OR two Advisor T3s. You cannot use one of each. Also, you must enable 3.0
Auto-Detect/Termination mode. Manual control does not work.
3.4.1 Removing Expansion Cards
You can remove expansion cards using two tools:
•Standard (flat blade) 3/16” screwdriver
•LeCroy Extraction Tool (part number 230-0160-00)
LeCroy Corporation 53
Chapter 3: InstallationUSB Protocol Suite User Manual
To remove an expansion card, follow these steps:
Step 1 Unplug the system from AC power and turn the system so the expansion port is
facing you. Note the two retaining screws and the holes for the extraction tool that
are located on the panel of the expansion card.
Note: The example shows a different expansion card, but the removal method is
the same.
Step 2 Insert the extraction-tool prongs into the holes in the expansion card panel.
Note: If the prongs do not slip easily into the holes, use a small nail file or similar
device to remove paint from the prongs.
Step 3 Rotate the extraction tool to a horizontal position to lock the prongs into place and
make a handle.
54LeCroy Corporation
USB Protocol Suite User ManualChapter 3: Installation

Input Equalization
Depending on the hardware version of your system, there are two ways to control input
equalization. One method requires you to set three time constants, or use the defaults.
The other method allows you to select either Hi or Low, or use the default. The method
appropriate for your connected hardware is enabled.
For advanced users only: You can change the values for the “other hardware” by
checking Enable Both Eq modifications. For example, you might want to do this if you
use the same file for both Advisor T3 and Voyager M3i.
3.5.6 USB 3.0 Cabling and Signal Integrity
The Analyzer requires two connector discontinuities. In addition, bus-powered devices
are susceptible to voltage drops on VBus.
To maintain the best possible signal integrity for all devices under test, use high-quality
cabling and use the shortest possible cable lengths. Do not "stress" the system by using
long or low-quality cabling that might result in signal degradation.
If you suspect signal integrity problems in capture situations, you should first try using
shorter and higher-quality cables to see if this rectifies the problem.
64LeCroy Corporation
USB Protocol Suite User ManualChapter 3: Installation
3.6 Your First USB Recording
After installing and launching the software, you can test the system by performing the
following steps:
Step 1 Connect a USB cable to each of the two connectors on the Analyzer module,
then connect the other ends to the USB device under test and USB host system.
Note: Whenever you do connect/disconnect testing, always plug/unplug the “B”
connector on the Analyzer, to insure that the Host detects the event properly. In
some cases, using the “A” port for this purpose can cause the Host to
misinterpret the terminations.
Step 2 Select Setup > Recording Options on the Menu Bar.
Step 3 Select the General tab to display a dialog box showing factory default settings,
such as Snapshot and 4 MB buffer size. For the first recording, you can leave
these settings unchanged. Under Recording Channels, select 2.0 to record
USB 2.0 traffic.
Note: Items not supported on your hardware are grayed out or not shown.
Step 4 Click OK to activate the recording options you selected.
Step 5 Turn on the USB devices that are to be tested and cause them to generate USB
traffic.
LeCroy Corporation 65
Chapter 3: InstallationUSB Protocol Suite User Manual
Step 6 Clickon the Tool Bar.
The system starts to record the USB traffic immediately. After 4 MB of traffic are
recorded, the Analyzer uploads the data and displays the packets in the trace
window.
Step 7 To terminate recording before the snapshot automatically completes,
clickon the Tool Bar.
When the recording session finishes, the traffic uploads from the Analyzer to the
hard drive on your PC as a file named data.usb or the name you assigned as the
default filename. While the file is uploading, you should see a brown progress bar
at the bottom of the screen. When the bar disappears, the data has uploaded to
disk.
Step 8 To save a current recording for future reference, select File > Save As on the
Menu Bar.
OR
Clickon the Tool Bar to display the standard Save As window.

3.6.1 Trace View Features
After the recording terminates, the results display.
•The packet view display uses color and graphics to document captured traffic.
•Packets are on separate rows, with individual fields both labeled and
color-coded.
•Packets are numbered sequentially (as recorded), time-stamped (with a
resolution of 2 ns on 3.0 signalling), and highlighted to show the transmitted
speed (low-speed, full-speed, high-speed, or superspeed).
•You can name and save display formats for later use.
•Data fields can collapse to occupy minimal space in the display.
You can start the application from the Desktop or from the installed directory.
The display software can operate independently of the Analyzer. When used without the

3.7 Notes on Vista and Windows 7 Directory
Protections
3.7.1 User Data File Paths
Windows™ Vista and Windows 7 institute a policy which prevents user data from being
written into the Program Files directory/folder. It was common for applications written for
Windows XP (and earlier) to use the Program Files folder to store user data. LeCroy and
CATC products used this folder as a default folder for storing trace files, user option files
(default.opt, default.rec), scripts, and so on. The default folder for USB Protocol Suite
was:
x:\Program Files\Lecroy\USB Protocol Suite\…
Windows Vista and Windows 7 make such paths illegal directories for user data. For
Windows Vista and Windows 7, files that are accessible by different user accounts must
be in the path
x:\Users\Public\…
To preserve the ability of multiple user accounts to access all the LeCroy files that were
accessible in Windows XP when using Windows Vista and Windows 7, files that were in
the Program Files path in Windows XP are now in:
In some cases, such as paths stored in the Recording Options .rec file, the application
silently changes this path, so that the Windows Vista and Windows 7 operating systems
will accept it as valid.
USB Protocol Suite on Windows XP still uses the Program Files directory. However, if a
Recording Options file that was created on a Windows 7 system is used on a
Windows XP system, trace files will be probably be recorded to a new Windows XP
directory called
This is a legitimate path on a Windows XP system, so there are no conflicts with the
operating system.

The USB Protocol Suite application can function with or without the Analyzer. When used
without an Analyzer, the program functions in a Trace Viewer mode to view, analyze, and
print captured protocol traffic. The software also allows you to view trace files created by
the LeCroy USB Chief™, USB Advisor™, USB Detective™, USB Inspector™, and
USB Tracer™/Trainer™. Opening a file created with any of those Analyzers displays a
screen asking if you want to convert the old file to the new format under the name

4.2.2 Exporting to USB 2.0 Generation Files (.utg files)
Before exporting to a .utg file, first make sure the .usb file contains traffic for only one
device:
Step 1 Hide all other device addresses in the trace, leaving only the address of your
device and the Address 0 (the default enumeration address.)
Step 2 Save to a new file using the All and
Do not save hidden Packets/Transactions/Transfers selections.
Step 3 On the new file, you can now
Export… Packets to USB 2.0 … Text File (.utg) …
Step 4 If the captured file was Hi Speed and was recorded in Auto-Speed Detect mode,
you must add a ping=here statement before the first SOF packets in the .utg file.
This is required because, when the capture is made in Auto-Speed Detect mode,
the first "Ping" sequence is not captured in the trace file.

Display Stacking View.
Stacking conserves space in the trace view by displaying repeating
items (or item groups) as one item, along with the number of repeats.
For USB 2.0, stacking items (or item groups) can be:
•SOF
• Chirp (merges J's and Ks into one stacked display unit)
• NAK'ed (split) Transaction
For USB 3.0, stacking items (or item groups) can be:
• TSEQ
• TS1 with same Link Functionality
• TS2 with same Link Functionality
• LFPS with same Type
•LUP
•LDN
• NAK'ed Transaction
Note: Items are grouped regardless of any intervening Skip
Sequence, Electrical Idle, or Logical Idle symbols. If any of these
occur during a stream of the repeating stacking item, they are not
displayed.

4.6 Status Bar
The Status Bar is located at the bottom of the main display window.
Depending on the current activity, the left side of the bar has segments that indicate the
hardware, status, size, activity, and buffer.
The right side of the bar has segments that indicate port status, link status, and
search direction.
4.6.1 Recording Progress
When you begin recording, the Status Bar displays an indicator.
As recording progresses, the indicator changes to reflect the recording progress
graphically:
A black vertical line illustrates the location of the Trigger Position that you selected in
Recording Options.
•Pre-Trigger progress is in the field to the left of the Trigger Position in the
before-trigger color specified in the Display Options.
•When the Trigger Position is reached, the indicator wiggles as it waits for the
trigger.
•After the trigger occurs, the field to the right of the Trigger Position fills with the
after-trigger color specified in the Display Options.
•When recording is complete, the upper half of the progress indicator fills with
white, indicating the progress of the data upload to the host computer.
You should be aware of two exceptional conditions:
•If a Trigger Event occurs during the before-trigger recording, the
before-trigger color changes to the after-trigger color to indicate that not all
the expected data was recorded pre-trigger.
•When you click Stop before or after a Trigger Event, the Status Bar adjusts
accordingly to begin uploading the most recently recorded data.
The indicator fills with color in proportion to the specified size and actual rate at which the
hardware is writing and reading the recording memory. However, the indicator is
normalized to fill the space within the Status Bar.

4.6.2 Recording Status
During recording, the current Recording Status is in a segment. When you activate the
Record function, this segment flashes a message depending on the selected
Recording Options, such as Triggered or Uploading.
After recording stops,
•The flashing message changes to Uploading data–x% done (x% indicates
the percentage completion of the data uploading process).
•The traffic data copies to disk (overwriting any previous version of this file)
using the default file name data.usb. You can also create a file name by
specifying one in the Recording Options dialog box.
To abort the upload process:
•Press Esc on the keyboard
OR
•Again clickin the Tool Bar.
You are asked if you want to keep or discard the partially uploaded data.
Note: While uploading is in progress, clicking the Stop button again opens a dialog
that allows you to do a partial upload, flush the current file, keep what has
uploaded at this point, or to continue uploading.
The Partial Upload button enables when you have partially uploaded data. When you
click Partial Upload, a dialog box displays options on what portion of data you want to
upload again.
